The True Rainbow Dash: A changeling story

"Dash we've been walking for like almost an hour... Are we almost there yet?" Scootaloo said.

Rainbow Dash stopped.

"Scootaloo... I lied to you, I didn't bring you here to do camping" Dash said.
"Huh? Then why are we here for?" Scoot said, dissapointed.
"Because I need YOUR help" Dash said.
"MY help?????? You are way too awesome to need MY help!" Scoot said.
"Well, my awesomeness can't help in this situation. So... I have something I gotta tell you and show you and then you gotta help me with it squirt but you must promise me that you will trust me no matter what that thing is." Dash said.
"I pinkie promise to trust you no matter what that thing is!" Scoot said.
"Good" Dash said.

Rainbow Dash shifted to her changeling form.

"I'm a changeling" Dash said.

Scoot just froze there staring at Dash.

"D...D...Dash?" Scootaloo said, in shock.

"Don't panic ok? Look I'm as scared as you are... I discovered this this morning ok? Look I'll explain everything" Dash said.

After Dash was done explaining everything that happenned to her, Scootaloo calmed down.

"But this is horrible! We gotta find a way to prove that you are you!" Scootaloo said.
"And thats why I need your help. I thought you could help me prove that... Now we just gotta find how" Dash said.
"YES YES YES I HAVE AN IDEA! I KNOW SOMETHING ONLY YOU CAN DO AND THAT WILL PROVE EVERYONE THAT YOU ARE THE REAL RAINBOW DASH... A SONIC RAINBOOM!!!!!!!!!" Scootaloo said.
